A Zodiarts is created when an ordinary human uses a [[TransformationTrinket Zodiarts Switch]] to create an avatar body of Cosmic Energy, transforming and giving him/her incredible powers. The human (known as a "Switcher") can use the Switch to transform freely between his/her normal and Zodiarts forms as many times as he/she wishes.

After a certain number of uses (catalyzed by the user's [[VillainousBreakdown rage and negativity]]) the Zodiarts Switch will mutate into a form known as "Last One". If the Switcher uses the Zodiarts Switch after this happens, their human body is ejected by the Zodiarts body upon transformation. While this increases the Zodiarts's power, it [[DeadlyUpgrade carries a risk]] that the Switcher will not be able to turn back to normal.

%% Only include *general* Zodiarts tropes in this list. Tropes that apply to specific Zodiarts can be filled under that Zodiarts' individual entry, below.

!General Tropes* AllEncompassingMantle: Exclusive to the Horoscopes. [[TheGlovesComeOff Until they junk them, that's when shit goes down.]]* AnimalMotifs: Sometimes done with Zodiarts based on constellations that aren't animals. Pyxis (also known as the Mariners' Compass) is specifically bug-like, and even Altar (self-explanatory) has bug-like mandibles which combined with her PlayingWithFire ability, makes her a [[StealthPun firefly]].** Perseus has a wolf motif to him. Medusa's head (re: the original legend) is even incorporated into the design so he's got a bunch of snakes as well.** Libra has antennae and a smaller mantle under his cloak that make him look like a cockroach. And Leo actually did call him a cockroach upon [[spoiler:Libra's HeelFaceTurn.]]** Virgo invokes this with deliberately bird-like wings that even shed feathers.** Inverted with Dragon - the dragon bits are shifted towards the arms, making him look nondescript.** Aquarius is the first to knowingly avert this. Though she does look slightly like a jellyfish.** Taurus, of course, looks similar to a giant bull.** [[spoiler: Sagittarius]] has a bird motif, as it is the scientific name of the secretarybird.*** [[spoiler:It is a misconception that the myth behind the constellation of Sagittarius, the Archer, is that it was the centaur Chiron, who is actually represented by the aptly named constellation Centaurus. Sagittarius represents the satyr Crotus, so if the Sagittarius Zodiarts was going to be accurate, it'd be a man with goat legs and horns.]]*** His Super Nova form's design is a mixture of a [[spoiler: Horoscopes Switch and a bug]]. Interesting enough, in this form he has his own version [[spoiler:of a Rider Kick and Punch]].** Averted again with Gemini, who resembles a jester.** Not surprisingly, Pisces is a fish.* DeadlyUpgrade: Kengo implies that when using a Zodiarts Switch in its "Last One" stage, the user may not be able to turn back. Considering their soul effectively leaves their body in a coma to control the Zodiarts body, he probably has a point.** Gentaro mentions in Episode 8 that Miura (Orion Zodiarts) is still in hospital. [[spoiler:Then episode 13 comes. He's well, but not going back to Amanogawa due to withdrawal symptoms.]]** Episode 14 reveals that when a former switcher is given a new switch, it immediately enters Last One state.** Episode 14 also reveals the true final form of a Horoscope, its Supernova form! ** Episode 15 reveals that a Zodiarts can surpass the Last One state, which could lead to them becoming a Horoscope. [[spoiler: And Episode 22 revealed the first student to become a Horoscope.]]* DrunkOnTheDarkSide: The users tend to become more irrational and insane as they continue to use the Switch. This is undone with its destruction, however.* EvilFeelsGood: A frequent consequence of using a Zodiarts Switch. At least one former Switcher - Miura (Orion) - develops withdrawal symptoms after his Switch is destroyed.* FromNobodyToNightmare: Invoked in the same way as ''Series/KamenRiderDouble''.* TheGlovesComeOff: The Horoscopes junk their black capes when they go into battle. Not that there's some kind of RestrainingBolt in action, just RuleOfCool really.* MadeOfExplodium: The released Cosmic Energy could take out an entire city block or more, so Fourze has to be careful when using a Limit Break.** Of note, defeating the Zodiarts itself doesn't destroy it completely - the only way to take it out for good is to destroy the Switch by turning it off once and for all.* MagicAndPowers** PersonalityPowers: The Zodiarts evolve in reaction to their host's abilities and desires. For example Unicorn gained a sword due to Nitta's fencing ability and Hound fit Teruhiko's fondness for chains as its main weapon.* MonogenderMonsters: Averted in a fashion similar to ''Series/KamenRiderDouble''. Like the Dopants, uncovering the true identity of a Zodiarts is part of the story. To add to the mystery, the Zodiarts refrain from speaking, have their voices digitally distorted, or a separate voice actor is used until their identity is revealed.* MonsterOfTheWeek* OneWingedAngel: Some of the "Last One" transformations.** Ramped UpToEleven #14 [[spoiler: as Horoscopes have the ability go Supernova turning them into giant monsters!]]** [[spoiler: Taken beyond eleven in in #15. What is beyond Last One? The evolution to a Horoscope-level Zodiarts!]]* ShoutOut** Lynx, with its SuperSpeed ability, brings to mind the [[Series/KamenRiderDouble Smilodon Dopant]].** Leo is awfully similar to [[Series/KamenRiderKiva Rook the Lion Fangire]].** Capricorn takes after a goat not just in appearance; his affinity for music is a reference to Pan, the goat-like god in Myth/ClassicalMythology.* SortingAlgorithmOfEvil: the latter half of the series eschews normal Zodiarts to have [[spoiler:actual Horoscopes as [=MOTWs=], starting with Aries in #31.]]* StockSuperpowers* SuperpoweredEvilSide: The Zodiarts are pretty much extensions of their anger and wrath, but sometimes they can get even worse. Case in point: [[spoiler: the case of Cygnus who was, in fact, a student's SplitPersonality.]]* WeaponOfChoice: Some of the Zodiarts have one. These are: Orion, Monoceros, Altar, Hound, Perseus (regular) Libra, Virgo, Aries, Capricorn and Taurus. (Horoscopes)** NamedWeapons: All of them are named. Wiki/TheOtherWiki shows their names.* VillainousBreakdown: Apparently the most effective way to accelerate a Switch's evolution to its "Last One" stage.

Founder of Amanogawa High School, chairman of the board, and former scientist and pioneer of lunar research with connections to NASA and the Russian Federal Space Agency.

He is secretly the mastermind behind the Zodiarts, and has been distributing the Zodiarts Switches amongst the students of his school for reasons unknown. His eyes often glow with an [[RedEyesTakeWarning unearthly red light]], and he possesses the ability to wield Cosmic Energy in a raw form. [[spoiler: At #32, Libra finds out that his Zodiarts form is Sagittarius and he transforms into it in #42.]]

* AffablyEvil: Gamou is the type to call you over in the cafeteria to try a new soup he's made himself, then a few hours later [[spoiler: break into your headquarters and kill your best friend in front of your eyes,]] apologize for the fuss and thank you for finding the soup delicious enough that he's added it to the menu. What a nice guy.* AmbiguouslyHuman: Because Gamou has been using the Switches for so much longer than anyone else, even his human form has power over negative Cosmic Energy that lets him exhibit control over other Zodiarts and even other Horoscopes, usually associated with his eyes turning a bright red color.* [[spoiler: ArrowsOnFire: Which are called Apostolos]].* [[spoiler: AscendToAHigherPlaneOfExistence: His ultimate goal is to meet [[{{Precursors}} the Presenters]] and evolve beyond human.]]* AsskickingEqualsAuthority* BigBad: The ringleader of the Zodiarts.** NonActionBigBad: He leaves the more direct approach to his subordinates. [[spoiler:Until #42, which ends with a FinalBossPreview. Then he takes the straight role of BigBad.]]* BishounenLine: [[spoiler:Sagittarius]] looks like most Kamen Rider final bosses- huge and overdesigned. [[spoiler:Supernova Sagittarius is far more streamlined, almost resembling a Kamen Rider himself.]]* BookEnds: [[spoiler:notice what happens at the beginning and ending scenes of #45?]]* [[spoiler:BystanderSyndrome: When asked what will become of Japan after his endgame, he pretty much responds that it's up to them. They want to follow his example? good. Japan gets destroyed as he ascends? Not his problem.]]* [[spoiler:DrunkOnTheDarkSide: Gets more and more unhinged as he gets closer to his goal.]]* [[spoiler:EntitledBastard: After Libra gives his life to protect him, Gamou states that [[ItsAllAboutMe he's the sun and Libra was just a planet orbiting him]] and that's why Libra saved him, not because he actually cared.]]* EvilOverlooker: The newest version of the OP (#35 on) shows him alongside the Horoscopes in this manner.* EvilTeacher* {{Expy}}: Of [[Series/KamenRiderDouble Ryubee Sonozaki]]. BigBad from day one? Check. [[spoiler: Extremely powerful monster form? Check. Plan involves causing the apocalypse? Check.]]* {{Foil}}: To Gentaro in that where Gentaro is a MagneticHero who cares more about his friends than anything else, Gamou [[spoiler:[[ItsAllAboutMe cares only about himself]] and sees no value in friendship at all.]] * [[spoiler:AGodAmI]]* GoKartingWithBowser: Granted, the club has yet to figure out he's the BigBad, but he did go out of his way to cook for Kengo's birthday. A big part of what makes him so AffablyEvil. He also helps the KRC in the climax of TheMovie by being one of the forty switchers.* [[spoiler:{{Greed}}]]* [[spoiler:HeroKiller]]* HiddenAgendaVillain: It takes a while for it to come out that he distributes the Zodiarts Switches to students in order for them to evolve into the remaining Horoscopes.* [[spoiler:HeelRealization: The heroes fighting him, not with hate, but with ThePowerOfFriendship manages to make him see the light in the end.]]* [[spoiler:HoistByHisOwnPetard: Very nearly happened to him in #46 when he discovers as he's preparing to AscendToAHigherPlaneOfExistence that while its happening he's completely powerless. If it weren't for Libra TakingTheBullet for him, he'd have been finished.]]* [[spoiler:{{Hypocrite}}: While he says he never had a friend and that friendship is useless, he was visibly saddened by Emoto's betrayal and subsequent death and the next arcs are basically him trying to find new companions for his space travel (even going so far as to ask Hayami, who he was treating like crap up to that point, to come with him).]]* ItAmusedMe: Hayami mentions that this is why there was a "bonus question" in the astronaut qualification test. -->"He was having a little fun."* [[spoiler:ItsAllAboutMe: Gets called this in #45, but ''really'' shows it when Libra sacrifices himself for him.]]--> '''Gamou''': [[spoiler:I am the sun, he was simply a planet that orbited me. [[EntitledBastard It's only natural he'd defend me]].]]* JediMindTrick: How he got [[spoiler:the police to forgo their investigation of the school]].* [[spoiler:KarmicDeath: Dies due to the strain his switch put on him. He even lampshades it.]]--> '''Gamou''': [[spoiler:I pushed my evolution too much.]]%%* [[spoiler:LackOfEmpathy : If Gentaro and Kengo said in #46 was true]].%%* [[spoiler:MacrossMissileMassacre]]* MeaningfulName: [[spoiler:In a bit of a stretch, the kanji that comprise Gamou's first name are translated as "bright light", which is one of the epithets of the god Apollo, who was also the god of archery, and Sagittarius is primarily identfied as "The Archer", despite its common and mistaken depiction as a centaur.]]** [[spoiler:Emoto illustrated this connection to Apollo further when he descibes Gamou as "like the Sun".]]* [[spoiler: MightyGlacier: Monstrously powerful, but his reliance on mostly long range attacks means that he doesn't have to move very fast.]]* [[spoiler:MyGreatestFailure: He states to Kengo in #34 that he felt sorry for not saving his father, but that might be a lie.]]* [[spoiler:NietzscheWannabe: He thinks that friendship is useless]].* NoNameGiven[=/=]OnlyKnownByTheirNickname: Initially, as "The Red-Eyed Man".* [[spoiler:OneWingedAngel: Towards the end of the series becomes the Sagittarius Zodiarts. He also gets a Supernova form on top of it.]]* OrcusOnHisThrone: He's mostly been seated on his chair and talking to the Zodiarts. [[spoiler:Until he transforms in into the Sagittarius Zodiarts.]]* PetTheDog: For a toku villain, he seems unusually committed to having his minions not die. He chooses to send those that repeatedly fail him to the Dark Nebula, and he makes an effort to have Virgo rescue those who are taken out by Fourze in space. He even wipes out memories of some of his fellow Horoscopes as an alternative to the Dark Nebula. This can be {{justified|Trope}} since he only seems to want the Horoscopes Switches instead. [[spoiler: When he is eventually forced to kill off one of the Horoscopes, he does seem legitimately remorseful about it.]]** [[spoiler:He seemed to generally like (or at least be amused by) Yuuki even before she said she could hear "The Voice of Space"; after that, he tries to recruit her and when he fails laments that he'll be all alone in the end.]]* [[spoiler: PlayingWithFire]]* [[spoiler: {{Pride}}: As his statement in #46 believed.]]* [[spoiler: RainOfArrows]]* [[spoiler:RasputinianDeath: Takes the FinishingMove of ''every'' one of Fourze's States, including Rocket States, in a row (two from Cosmic States), a beat down from Gentaro (read: '''not in Fourze's Suit!'''), and finally a ''quadruple'' Limit Break from Base States to finally take him down.]]* RealMenWearPink: who would've thunk that the BigBad is an excellent cook?* [[spoiler:RedemptionEqualsDeath: After Fourze finally defeats him, Gamou finally accepts the latter's belief in the ThePowerOfFriendship -- and they do the SecretHandshake. However, Gamou realizes that [[SuperpowerMeltdown his abuse of Sagittarius is finally taking a toll on his body]]. He then walks off and transforms into Aquarius Zodiarts so he could use its healing powers to fix the Core Switch, reviving Kengo in the process, before he fades away into Cosmic Energy.]]* RedEyesTakeWarning* [[spoiler: ShedArmorGainSpeed: His Nova form discards armor, making him fast and powerful enough to defeat Kengo's Core Child powers.]]* [[spoiler: ShootTheDog: In the end, he orders the death of quite possibly his closest comrade and only friend, Emoto. After retrieving Virgo's Switch, he actually seems to feel bad about what he did. For about the span of a few seconds.]]* [[spoiler:VillainousBreakdown: After Kengo denies him the entry into the Dark Nebula, he loses his composure and gets pissed, even beating around Leo a bit before unlocking his SuperMode, though he gets a bit better]].* [[spoiler:VillainsDyingGrace: After being defeated by Fourze, resulting in a SuperpowerMeltdown that will kill him, he uses the Aquarius Zodiarts switch to revive Kengo before dying.]]* WalkingSpoiler: Good lord...* WellIntentionedExtremist: If Scorpion is to be believed, he's apparently trying to benefit mankind. [[spoiler:It seems he believes that the destruction of Japan would be worth forcing what will remain of humanity to evolve just as he did.]]** [[spoiler: Overlaps with SocialDarwinist.]]* [[spoiler:UltimateLifeform: Considers himself this.]]--> '''Gamou''': [[spoiler:I am the apex of human evolution, the Sagittarius Zodiarts.]]* [[spoiler:YouMonster: The Kamen Rider Club's reaction to him completely disregarding Libra sacrificing himself for him.]][[/folder]]

[[folder:Horoscopes]]!Horoscopes

A group of twelve Zodiarts, each representing a constellation of the WesternZodiac. They are direct subordinates to Gamou, giving out Zodiarts Switches on his behalf, and are notably stronger than regular Zodiarts. A Horoscopes member can be identified by the distinctive black robes they wear, which act as {{Power Limiter}}s to their true potential.

A Horoscopes is created when a Zodiarts exceeds the Last One stage of the Zodiarts Switch, reabsorbing its human body and evolving into an even more powerful form. Only certain talented individuals have the potential to become a Horoscopes; thus, it is the Horoscopes' mission to find and awaken all twelve of their kin.

* BadassLongRobe* CoDragons* DeadlyUpgrade: Kengo's scan of Scorpion Nova implies the supernova power up may be carry some risk to the Zodiarts itself.* FiveBadBand: The initial Horoscopes fit into this fairly well, even though they are not all active at once.** BigBad: The Red-Eyed Man/Mitsuaki Gamou[[spoiler:/Sagittarius]]** TheDragon: Virgo ** EvilGenius: Libra** TheBrute: Leo ** DarkChick: Scorpion[[spoiler:/Aquarius/Gemini]]** [[spoiler:SixthRanger: Cancer/Capricorn/Aquarius/Gemini]]** [[spoiler:SixthRangerTraitor: Aries/Taurus/Pisces]]* IAmNotLeftHanded: According to offical materials, their robes [[PowerLimiter limit their power to some degree]] and casting them off allows them to fight at full power.* {{Mooks}}: The Star Dust Ninjas called Dustards, which the Horoscopes can create in large numbers.** EliteMooks: Leo Dustards, which Leo is able to create [[spoiler:apparently due to being given the Switches of all the Horoscopes except Sagittarius and Libra.]] They have hair and are considerably more powerful than normal Dustards, but are only created in groups of two. * OneWingedAngel: The Red-Eyed Man can give them this ability by infusing them with a "Supernova". It's stated only the Horoscopes can do this.** The Horoscopes are pretty much OneWingedAngel forms themselves, being the result of someone who exceeded Last One and evolved into them. It doesn't even have to be one of the twelve WesternZodiac signs, as [[spoiler:Scorpion was the Canis Minor Zodiarts before evolving and Pegasus becoming Cancer. [[SerialEscalation Even from there, they can be infused with supernova into a further form, as shown in episode 14!]]]] Worse, [[spoiler: Cancer didn't need Gamou's help unlike Scorpio. No, he went to Cancer Nova ''all by himself''!]]* StandardEvilOrganizationSquad* WesternZodiac

The Zodiarts representing the constellation Scorpius, the Scorpion. It is the first of the Horoscopes to be seen, and distributes Zodiarts Switches to those who wish to gain revenge. In battle, it uses powerful kickboxing attacks.

* [[AbsurdlySharpBlade Absurdly Sharp Stinger]]: The stinger can pierce through the bottom of a metal trolley [[spoiler:and stings Gentaro]].* BewareMyStingerTail: It has an extendable scorpion tail on its head that can inject a deadly poison into whoever it stings. [[spoiler:It was able to sting Gentaro and JK, and merely ''grazing'' Shun has that effect, but the three were saved with the Medical Switch.]]* BigCreepyCrawlies* [[spoiler: DarkChick: Being the only lone female of the original Horoscopes, this was obviously her role. Later replaced by Aquarius.]]* DeathByIrony: [[spoiler:Sonoda-sensei's grudge on Gentaro ultimately [[VillainousBreakdown defeated her]]. For added irony, said breakdown was caused by Miura rejecting the Orion Switch after it was offered again to him.]]* ExtremityExtremist: Doesn't rely on its hands at all during combat, preferring either its legs or [[BewareMyStingerTail Stinger Tail]]** Has now become somewhat of a BareFistedMonk, what with more common usage of the hands in combat, though will still prefer the legs.** [[spoiler:KickChick]]* [[spoiler:FateWorseThanDeath[=/=]AndIMustScream: Gets imprisoned within the Dark Nebula as punishment for screwing up her last chance]].* [[spoiler:{{Irony}}: If "The Melancholy of Sarina Sonada" segment of the Net Movies are anything to go by, Sonada had considered giving Yuuki a Zodiarts Switch but deciding against it since Yuuki had no real problems. Had Sonada given Yuuki a switch, regardless of if she was troubled or not, there was a good possibility that Yuuki would have evolved into Gemini, saving her from being banished to the Dark Nebula.]]* ItsPersonal: Seems to be his preference as to whom he hands out Zodiarts Switches. Which is in line with both myths of Scorpius, where the Scorpion was sent to kill Orion due to a god (Apollo in one and Gaea in another) being offended by him.** [[spoiler:She herself grows a grudge against Fourze for constantly ruining her plans. [[DeathByIrony It leads to her defeat]], as she becomes so fixated on killing him she doesn't even consider taking a VillainExitStageLeft as she'd done many times before.]]* JackOfAllStats: Great at attacking with its bare fists and feet and pretty much sends Fourze flying in almost every battle they have.* MeaningfulName: The syllables in her name can be rearranged to form "Sasori na no da" or "I am the scorpion."* NiceJobFixingItVillain: when you think about it, it's this guy's preference for choosing Zodiarts that the Kamen Rider Club was formed in the first place.* OneWingedAngel: [[spoiler:[[OurCentaursAreDifferent Transforms her bottom half of her body into a giant scorpion form]] called Scorpion Nova in Episode 14]].** From what Gamou says, [[spoiler:all 12 Horoscopes have the ability to become this]].* RedEyesTakeWarning* [[spoiler:SamusIsAGirl: Despite the masculine voice, its true identity is Sonoda-sensei.]]* ScaryScorpions* StarterVillain: Is the first of the Horoscopes to show up and Fourze's first real challenge, but was beaten without even a MidseasonUpgrade, and was considered in universe to be incompetent picking Switchers. * SuperpowerLottery: Inverted. While the other Horoscopes have powers along the lines of invulnerable armor, the ability to steal souls, and the capacity to warp spacetime, having a poisonous tail really fails to measure up. Heck, Scorpio could probably have been beaten by one of the higher-end standard Zodiarts, like Dragon or Musca. * ThisCannotBe: [[spoiler:Her reaction to Fourze managing to defeat her despite having already gone OneWingedAngel.]]* VillainExitStageLeft: Tends to do this when Fourze is coming close to victory. [[spoiler:Until Episode 14, when [[ItsPersonal her growing grudge against Fourze]] for being too much of a SpannerInTheWorks [[VillainousBreakdown gets in the way of her common sense]].]]* VillainForgotToLevelGrind: Its problem wasn't getting weaker, but Fourze was getting stronger and it wasn't. It had to be ''given'' its OneWingedAngel, as opposed to all the other Horoscopes who got theirs without help.* VillainousBreakdown: [[spoiler:Develops one in Episode 13, having grown tired of the Kamen Rider Club's interference. ''Really'' loses it when Miura rejects the Orion Switch, not only trying to kill him, but going pretty much berserk, gunning for Gentaro's head.]]* WithMyHandsTied: [[ExtremityExtremist Maybe not on purpose]], but it doesn't even bother using its hands in its first fight with Gentaro.* YouHaveOutlivedYourUsefulness: Subverted. [[spoiler:For falling to Fourze even after going OneWingedAngel, Gamou confiscates her Switch and passes the duty of passing Switches to Principal Hayami/Libra for the time being.]]** [[spoiler: Played straight in #18 after she pleads for her Switch back but is easily defeated by Meteor. She is imprisoned in the Dark Nebula by Virgo as punishment.]]

!!Libra/[[spoiler:Kouhei Hayami]]

The Zodiarts representing the constellation Libra, the Scales of Justice. The second of the Horoscopes to appear, it possesses various powers of illusion and fights using a [[SimpleStaff Khakkhara shakujo]]. It only distributes Zodiarts Switches to those it feels have the potential to become Horoscopes, and personally mentors them to reach that point.

* TheBadGuyWins: [[spoiler:Succeeded in destroying the four stations in Kyoto and closing its Hole, which was the mission he was sent on, despite being defeated by Fourze. On top of this, he [[OneWingedAngel achieves his Supernova]] in the process.]]* BareFistedMonk: It should be noted that he seldom actually uses that staff when he fights in one of his disguises.* BadassBookworm: According to WordOfGod, cut scenes from #45 were going to depict him as this. Before becoming a Zodiarts, he was an astrophysics student, whom at some point met Gamou and joined the Zodiarts.* TheDogBitesBack: Has been threatened with banishment to the Dark Nebula quite a few times and was nearly put there at one point. [[spoiler: It sort of feels like this when he and Leo killed Virgo]]. Though this is more The Dog ''Barks'' Back, since he [[spoiler: had Leo do all the work, then proceed to mock Virgo after death]].* DragonWithAnAgenda: [[spoiler:mentions how he wants Taurus for ''his'' own, undisclosed-as-of-yet plans.]]* [[spoiler:DroppedABridgeOnHim: After taking a hit meant for Gamou[=/=]Sagittarius, he gets pelted through the Horoscopes switches-derived portal ''before it's disrupted and closed off for good.'']]** [[spoiler: To make things worse, if you pay enough attention, as he's drifting away, you can see Libra get vaporized by a bolt of lightning. He's not trapped in the Dark Nebula or hurtling through space. Libra is flat-out ''dead''.]]* [[spoiler:EnemyMine: Becomes an unofficial member of the Kamen Rider Club after he sees an YouHaveOutlivedYourUsefulness coming from a mile away. It turns out that he was just faking though.]]* EvilGenius: Amongst the Horoscopes, this seems to be his role. He is more manipulative and cunning than his comrades, and has found himself in the role of distributing Zodiarts as part of Gamou's master plan.* EvilMentor: How he goes about dealing with his prospect Zodiarts and [[spoiler:Scorpion]]. The Zodiarts he "mentors" even refer to him as "Master Libra".* [[spoiler:FakeDefector]]* [[spoiler:{{Famous Last Words}}: "Master Gamou...Did you see? The worth of my existence..."]]* TheForceIsStrongWithThisOne: [[spoiler: His supernova form allows him to detect those with the potential to become Horoscopes.]]* {{Foreshadowing}}: in #37, he expresses sentiments that the astronaut exam would be a good way to spot potential Horoscopes. [[spoiler:He got his wish at the end of #38, finding Taurus among the finalists.]]* [[spoiler:HeelFaceTurn: Joins the Kamen Rider Club to protect Ran, the final Horoscope. Part of it is fueled by regret for ruining kids lives, but most of it is because he realizes that Gamou plans on riding out the final bit of his plan solo, making him expendable.]]* [[spoiler:HeelRealization: After all of his actions, he finally admitted it. Subverted in that he was a FakeDefector]]* [[spoiler:KickTheDog: In #43, alongside Leo, he forced Yuki to push a switch to awaken her potential as the Gemini Horoscopes]]. * KickTheSonOfABitch: [[spoiler:Tricking Virgo into sending Cancer to the Dark Nebula. While he was doing it for his own interests, there's little doubt Cancer deserved it. Later on, he and Leo killed Virgo, though by that point, she too perhaps had it coming.]]* [[spoiler:KilledOffForReal: Meets his end when knocked into the Dark Nebula by Fourze, after which he's struck by lightning and killed.]]* KnightOfCerebus: Right after Makise is dispatched, ''this'' guy sealed the deal on the CerebusSyndrome.* LockedOutOfTheLoop: [[spoiler:He doesn't have a clue regarding Virgo's identity.]]* ManipulativeBastard* MasterOfIllusion: He possesses several illusory powers, most notably the ability to make itself and others look like other people. At one point he even fights Fourze while disguised as [[MirrorMatch a second Fourze]].* MasterOfNone: He doesn't have a lot of fighting capability and his illusion powers are only good for distraction.* MeaningfulName: His given name (Kouhei) means "fairness", which is in line with his balance motif.* [[spoiler:MookFaceTurn]]* [[spoiler:MyGodWhatHaveIDone: has this moment when he realizes just how many people's lives he ruined by giving out all of the astroswitches. Subverted in the end, as he turns out to be a FakeDefector.]]* [[spoiler:NominalHero: after his HeelFaceTurn. He's the first to admit he is only siding with Fourze to save his own skin, but he will protect Ran at any cost, even if he has to take on Leo without a switch.]]* PragmaticVillainy: really takes his role as a mentor to prospective Zodiarts seriously, but, of course, this only ties into the Horoscopes' goal of completing their roster. His abhorrence towards Cancer also counts, since he believes the latter to be too much of a loose cannon anyway.* RedOniBlueOni: The blue to [[spoiler:Kijima]]/Cancer and Yamada/Aries' red.* ShockAndAwe: Can deliver a blast of electricity from his forehead. [[spoiler: Said electricity is even able to brainwash Zodiarts, as seen with Perseus.]]* SimpleStaff: Wields [[AllThereInTheManual The Dike]] that resembles a ''[[http://en.wikipedia.org/wiki/Khakkhara Khakkhara shakujo]]'', complete with jingling rings.* SmugSnake[=/=]SmugSuper: It's becoming clear that he gives himself too much credit for being "Master Libra" and thinks he's more important within the Horoscopes than he really is. Overlaps with his frustrations that he's turning into TheUnfavourite, while Gamou gives [[spoiler:Cancer]] more leniency.** He starts to become even more smug after obtaining the Eye of Laplace, not hesitating to brag about it in Leo's face.* [[spoiler:{{Taking The Bullet}}: Just when Fourze had the chance to finish off Saggitarius, Libra jumps in the way and takes a Limit Break to the chest in his place.]]* VillainExitStageLeft: Is able to teleport, leaving behind a blue nebula like light when he does so.* VillainousBreakdown: [[spoiler: When he realizes that ''he's'' next on the YouHaveFailedMe chopping block, he doesn't take it well and instead begs like a dog to be spared. This triggers his Supernova transformation, allowing him to perceive who is or can become a Horoscope, an ability that causes Gamou to (understandably) spare him.]]* [[spoiler:YouHaveOutlivedYourUsefulness: Sees this coming from a mile away, and defects before the statement can be uttered.]]

!!Virgo/[[spoiler:Kuniteru Emoto]]->Voice Actress: Creator/RieTanaka

The Zodiarts representing the constellation Virgo, the Virgin Goddess Astraea. The third of the Horoscopes to appear, Virgo has various powers of spatial manipulation, such as the power to imprison people in a PocketDimension called the Dark Nebula. She first appears fighting against Fourze in ''Movie War Megamax''. [[spoiler: In reality, Virgo is Emoto, an old ally of Kengo's father and Gamou, who killed Rokuro Utahoshi prior to the series.]]

* [[spoiler:TheAtoner]]* AnAxeToGrind: [[AllThereintheManual Rhodia]], a staff-like axe.* BitchInSheepsClothing: She's worse than Scorpio in this regard: Scorpio just stung people with poison, [[spoiler: Virgo threatens to take people into the Dark Nebula!]]* [[spoiler:BrokenPedestal: As Tomoko puts it:]]-->[[spoiler:"I couldn't believe you're such a bad person!"]]* [[spoiler:TheDogWasTheMastermind]]* TheDragon: While first Scorpion and then Libra served this role directly, Libra's description of her implies she's closer to this role the the first two.** [[spoiler:DragonWithAnAgenda: Gamou doesn't seem to know Virgo's other identity as Tachibana. For starters, he only learned of the latter's existence until the end of Aries' arc.]]* EarlyBirdCameo: Rather like Meteor, she appears in ''Movie Wars Megamax'' before debuting at the end of #18.* FlashStep* FreudianExcuse: Virgo's abhorrence towards Gentaro's praise of friendship is stemmed from [[spoiler:how Emoto's own TrueCompanions (him, Gamou and Kengo's father) ended up becoming.]]* [[spoiler:GoodAllAlong]]* GreenEyedMonster: [[spoiler: Emoto killed Rokuro because, as he states, he wanted to be the "Earth" rather than the "Moon."]] * [[spoiler:KilledOffForReal: Is killed by Sagittarius, Leo, and Libra for betraying the Horoscopes, making him the first Zodiarts to actually die.]]* MeaningfulName/[[spoiler:SignificantAnagram: Emoto backwards is otome, which means virgin.]]* PocketDimension: The Dark Nebula.* PowerFloats* PowerGivesYouWings* PowerLevels: She states in #32 that Fourze's Cosmic States makes him almost equal to her in strength.* PowerOfTheVoid: Don't believe me? In her tussle with Meteor in #22, she fired spheres of energy that would have possibly killed Meteor had he not move. Why? Because one kind of energy sphere Virgo can fire are '''black holes'''.* PragmaticVillainy: She objects to letting Taurus control and brainwash the school because individuality is ''kind of'' necessary for kids to want to use switches.* [[spoiler:RedemptionEqualsDeath]]** [[spoiler:RedemptionInTheRain]]* TheReveal: Her identity is quite well-hidden for most of the series. [[spoiler:Also, the series' opening scene with Kengo's father fighting against a red-eyed astronaut? It wasn't Gamou, it was ''this'' guy.]]** [[spoiler: And another reveal happened AGAIN in the very next episode, where she is Tachibana, the one who made Kamen Rider Meteor!]]* [[spoiler: SamusIsAGirl: An inversion.]]* TheSmurfettePrinciple: Currently the only member of the Horoscopes that's [[TertiarySexualCharacteristics clearly female.]]** Has now become one of the {{Dark Chick}}s of the season, what with the debut of the female Aquarius.** [[spoiler:Subverted.]]* SphereOfDestruction* StationaryWings* StoneWall: Prefers to utilize a very defensive fighting style, and can use her wings as a shield. Even her staff projects an invisible forcefield.** [[SarcasmMode Unless she taps into the power of ''Movie Wars Megamax'''s budget]], whereupon CGI wings and WireFu turn her into an outright LightningBruiser.* ThinkingUpPortals: Has the ability to create portals into space, much like Fourze's Cosmic States, as well as teleport people into the Dark Nebula.* [[spoiler:UnsettlingGenderReveal: What with the way Virgo looks, you'd think Virgo would've been a female behind the monster form. He isn't.]]* VillainTeleportation* WingedHumanoid

!!Cancer/[[spoiler:Natsuji Kijima]]The Zodiarts representing the constellation Cancer, the Crab sent to distract Heracles from his tasks. The fourth of the Horoscopes to appear, it possesses an incredibly [[SuperToughness tough skin]] that makes it hard to damage and [[AbsurdlySharpBlade sharp pincers]] that can slice through anything. It evolved from [[spoiler:Pegasus]].

* [[AbsurdlySharpBlade Absurdly Sharp Claw]]: His open claw is even capable of cutting through Fourze's shield, which is made of a ''super-durable metal called Astorium''.* [[spoiler:AndIMustScream: Libra and Virgo handle his punishment-Libra transforms him into the policeman that hounded Gamou in #27, and then tricks Virgo into sending him into the Dark Nebula, with his fan left behind.]]* DeadlyGame: [[spoiler:How he hands out Zodiarts Switches. He calls it [[NamesToRunAwayFromReallyFast "Open Mic From Hell"]]. You make him laugh? Congratulations, you get a Zodiarts Switch! You fail? Say goodbye to your '''soul'''.]]* DevilInPlainSight* FauxAffablyEvil: The fact he's polite and cheery just makes him ''more'' disturbing.* ForTheEvulz: How he approaches students with Switches. He basically asks if they want to have fun.** Made even worse in #27. [[spoiler: He takes a couple of athletes' souls away because none of them could make him laugh. And those that ''could'' were given a Zodiarts Switch instead!]]* {{Fireballs}}: One of his abilities.* GiantEnemyCrab: [[spoiler:Moreso when [[OneWingedAngel Supernova form]] kicks in (#27).]]* HamToHamCombat: One-sided, actually. During his fight with Meteor in #27, ''he would not shut up''.* HoistByHisOwnPetard: He would free the souls of the KRC he imprisoned should one make him laugh. [[spoiler: Ryusei engages him in battle and the sight is so hilarious to Kijima that he laughs...which is what Ryusei wanted him to do]].** Another thing that really bites him in the ass was [[spoiler: keeping the identity to Meteor to himself. If he had explained it to Gamou instead of promising to tell it later, he'd probably would still be a Zodiarts.]]* {{Irony}}: Cancer was supposed to pinch at the toes of Hercules while Hercules battled the Hydra. Hercules squashed him pretty easily. Here, Cancer's been ''really'' hard to destroy due to his powerful armor and the fact that he [[VillainExitStageLeft runs away just before Gentaro puts the finishing blow on him.]]* KillItWithFire: Thus far the ''only'' thing capable of damaging him.** Until #28, that is.* LaughablyEvil: Seems to be an intentional tactic of his to get under his opponents skin and confuse them. Makes him even more disturbing when he does stuff like [[spoiler:''steal people's '''souls''''']].* LightningBruiser: Fast, strong and takes most hits without a scratch on his shell.* MakingASplash: Another of his abilities.* MeaningfulName: The kanji of his given name can be read as "kani" (Japanese for "crab") based on the on'yomi pronunciation.* OneWingedAngel: [[spoiler:Cancer Nova. Worse? He managed to reach it ''without'' help!]]* PsychoForHire: Unlike the other Horoscopes who seem to be {{Well Intentioned Extremist}}s, Cancer is just a {{Sociopath}} who ''enjoys'' what he does.* RedOniBlueOni: The red to [[spoiler:Hayame]]/Libra's blue. (One of two)* SixthRanger: His role amongst the Horoscopes. The first to surpass Last One and become a Horoscopes since [[spoiler:Sonoda/]]Scorpion, he was also responsible for dishing out TheWorfEffect for a good while before his enemies one-upped him.* ShadowArchetype: As stated before, Cancer is one to Ryusei/Meteor. This was even Lampshaded by Cancer in 27. [[spoiler:Both are liars, hiding a secret from everyone. At first, Kijima was hiding his identity as Pegasus, though he did drop that act when he became Horoscopes. Ryusei, meanwhile, has been hiding his identity as Meteor.]] The parallels between the two of them are drawn constantly, with Ryusei even being the one to [[spoiler:discover Kijima's identity as a Zodiarts, and Kijima being the first person to learn of Ryusei's secret identity.]]* SuperToughness: And how! He's basically immune to ''everything'' that Fourze can throw at him, except for prolonged exposure to fire [[spoiler: and Kamen Rider Meteor's FinishingMove]].* WeCanRuleTogether: [[spoiler:Cancer makes this offer to Ryusei in exchange for keeping mum about his secret identity.]]* XanatosGambit: [[spoiler:His way of handing out Zodiarts Switches. They make him laugh? He hands out a Switch and a Zodiarts is let loose, continuing his mission. They don't? He gets their soul and becomes more powerful.]]* YouFightLikeACow: Mostly in his battle against Meteor.* [[spoiler:YourSoulIsMine: Type A. In #27, he was able to collect souls [[OurSoulsAreDifferent that look like rings]] and then snip them with his pincer, sending their owners into comas in the process. And he does it on the ''Kamen Rider Club'' in #28, almost snipping off Tomoko's had Ryusei not come in in time.]]

!!Aries/Tatsumori Yamada->Live Actor: Kazuma KawaharaThe Zodiarts representing the constellation Aries, the Ram with the Golden Fleece. The fifth of the Horoscopes to appear, he can control the mental facilities that regulate sleep, [[ConvenientComa tranquillising those who resist his will]]. His alter-ego is Tatsumori Yamada, a transferee to Subaruboshi from Amanogawa.

* AstonishinglyAppropriateAppearance: Well of course the Zodiarts that controls sleep would be the one that's a ''sheep''.* ChekhovsGunman: He was actually name-dropped in #17, ''14 episodes'' before he made his debut.* ConvenientComa: He can induce this upon anyone else. [[spoiler: Ironically, he's now in one of these.]]* [[spoiler: DealWithTheDevil: Gave one of these to Ryusei to save Jiro, in the cost of killing Fourze. He then paid his end of the bargain and revived Jiro.]]* [[spoiler:DeathByIrony: Almost. He's last seen lying comatose in hospital after losing his Switch.]]* TheDreaded: Among Subaruboshi students.* EarlyBirdCameo: In #30, after Meteor's brief altercation with Libra at Subaroboshi, someone in an Amanogawa uniform ominously walks past.* {{Expy}}: [[spoiler:He's an amoral AGHS student who uses his Zodiarts Switch to torment others ForTheEvulz and is actively opposing Hayami - just like Kijima, the Cancer Zodiarts.]]* HiddenDepths : Bastard that he is, it's still worth mentioning that [[spoiler:he doesn't back out of his arrangement with Ryusei. Mind you, it goes horribly wrong, but he did heal Jiro. Granted we never found out why so it could be pragmatic villainy]]* {{Irony}}: [[spoiler:Ryusei transfers to Amanogawa in search for Aries, except that Aries was the student who transferred to Subaruboshi in his place.]]* [[spoiler:KillerRabbit: Tatsumoi supposedly transcended the [[http://en.wikipedia.org/wiki/Lepus_(constellation) Lepus]].]]* [[spoiler:[[KarmicDeath Karmic Coma]]: After being defeated by Fourze, he is shown in the hospital in a coma, just like he did to his victims]].* MeaningfulName: The kanji in his name mean "dragon" and "guard/protect." In Greek mythology, Aries was a sacred golden ram whose fleece was guarded by a dragon.* [[spoiler:MonsterOfTheWeek: The other Horoscopes have been very dangerous, long-term threats; Yamada, on the other hand, was essentially this, with some backstory relevance for Ryusei.]]* NewTransferStudent: To Subaruboshi High.* [[spoiler:PowerupLetdown: He attempts to use Supernova against Fourze Cosmic States, but since he hasn't earned it himself or been granted it by Gamou, all that happens is his horns get bigger and removes the cape.]]* PrimaDonnaDirector[=/=]MadArtist: With his power over Subaruboshi, he forces all the students and teachers to act in the plays he writes and knocks out everyone who he feels isn't up to snuff. The KRC's general reaction to his scripts is "WhoWritesThisCrap", and he's shown to be lousy at casting too (he turns the Judo Club into the Space Club, and when he criticizes a teacher's English she protests that she teaches ''gym'').* RedBaron: He's known as the "Apostle of Sleep".* RedOniBlueOni: The red to Libra's Blue. (One of two)* RememberTheNewGuy: [[spoiler:Flashbacks to the first episode show that he was there even though he's only actually introduced much later. He was also mentioned in Episode 17 (Ryusei's debut) when both Gentaro and Sonoda note that Yamada was gone.]]* ShockandAwe: Emits electricity from his horn to paralyze people. Though, it's only use in the Net Movie so it might not be canon in the show.* SimpleStaff: [[AllThereInTheManual Coppelius Scepter]]. * SixthRanger[[spoiler:/SixthRangerTraitor]]: His role amongst the Zodiarts. [[spoiler: Though when he mouths off to Libra and decides to do whatever he feels like, you could consider it as him "betraying" Libra.]]* SquishyWizard: [[spoiler:His staff is pretty much his only means of one-upping his opponents. Once Fourze got [[SuperMode Cosmic States]], [[CurbStompBattle he went bye bye]].]]* StandardStatusEffects: Has the power to put anyone he touches with his staff to sleep or shut down the use of the Astroswitches temporarily.* TyrantTakesTheHelm: He took over Subaroboshi with an iron fist.

!!Leo/Kou Tatsugami->Live Actor: Kazutoshi YokoyamaThe Zodiarts representing the constellation Leo, the Nemean Lion. The sixth of the Horoscopes to be formally introduced in the television series, although he is featured in the opening title sequence and made a few non-speaking cameos beforehand. He is a proficient and deadly fighter. His true identity is Kou Tatsugami, Gamou's bodyguard.

* [[spoiler: AllYourPowersCombined: He has been entrusted the Switches of past Horoscopes by Gamou for safe-keeping. He can use them to take the forms of past Horoscopes like Aries, Aquarius, Cancer, Capricorn, even Virgo.]]* BerserkButton: He ''flipped'' after Gentaro approached Gamou without a regard for the latter's position. Gamou even held him back to make him keep his cool, but that didn't stop Leo from delivering a NoHoldsBarredBeatdown to Fourze unprovoked later that night.* TheBrute: Compared to its fellow Horoscopes Zodiarts. He's also the naturally tallest of the bunch.* TheCastShowOff: Kazutoshi Yokoyama was originally a stuntman for JAC, the stunt group for most Kamen Rider series. As such, he has some amazing untransformed fighting scenes, prime example would be his fight against Ryusei in #47.* CharacterTics: Manipulates walnuts in his hands, similar to Baoding Balls.* DarkAndTroubledPast: It is revealed in episode 47 that Tatsugami was nothing more than an ally-way brawler drunk on the power of his fighting prowess. It all changes when Gamou presents him with a Zodiarts switch.* DeathGlare* DragonTheirFeet: We've seen Fourze gain '''five''' powerups, three Horoscopes have been lost (though they assume that they could just get two of them back from the "Dark Nebula"), and this guy didn't act ''in any fashion''. [[JustifiedTrope Justified]] with his role as Gamou's bodyguard, instead of handing out Switches like Scorpio, Libra, and Cancer, an executioner like Virgo, or just fooling around like Aries.* DragonWithAnAgenda: [[spoiler:Leo hints at looking for a {{McGuffin}} called the "Core Switch", and mentions that it will surprise even Gamou, indicating that the latter has no idea. Though unlike most cases of this, he is completely loyal to the BigBad, and was apparently just trying to help further Gamou's plans.]]* DumbMuscle: Even if he managed to [[spoiler: help Libra's plan to get Picses]], he's not usually assigned to recruit Zodiarts because his general M.O. is "just press the switch already!"* EarlyBirdCameo* EvilCounterpart: Could serve as this to Either of the Kamen Riders, really. Like Gentaro, he is devoted to helping his friend (Though it does border on an unhealthy obsession at times), and like Ryusei he holds a great amount of martial arts expertise. [[spoiler:Also like the Kamen Riders, he can change out what Switch he's using to gain new powers.]]* {{Expy}} Lion-motif kaijin who takes powers from his comrades to fight and is TheDragon to the BigBad. Just like [[Series/KamenRiderOOO Kazari]].* TheJuggernaut: Thus far has been pretty much unstoppable to everything thrown at him, including ''both'' [[SuperMode Fourze Cosmic States and Meteor Storm]], and having the power to go with it.** In human form he can withstand the ''one-inch punch''. You know, that same punch that [[spoiler: '''killed Gentaro''']]?* [[spoiler:KickTheDog: In #43, alongside Libra, he forced Yuki to push a switch to awaken her potential as the Gemini Horoscope]].* [[spoiler:KilledOffForReal: Courtesy of Meteor Storm.]]%%* KingOfBeasts* MakeMeWannaShout: Has a powerful roar that can cause shockwaves.* MeaningfulName: His family name sounds similar to ''tategami'', meaning "mane", while the kanji used for his first name means "roar."* MightyGlacier: Tall, slow and ''powerful''. He can pummel both Cosmic States Fourze and Meteor Storm without breaking a sweat!%%* MoreTeethThanTheOsmondFamily* NoHoldsBarredBeatdown: see BerserkButton; Gentaro had little margin to transform, let alone defend himself from the assault!%%* RecruitedFromTheGutter%%* SuperSpeed%%* UndyingLoyalty* WolverineClaws: Can turn his forearms into a spectacularly large set.* YouHaveFailedMe: [[spoiler:tells Libra that should he fail the Kyoto mission, it will also be his last.]]

!!Capricorn/Toujiro Goto->Live Actor: Ryousuke KawamuraThe Zodiarts representing the constellation Capricorn, the sea goat. The seventh of the Horoscopes to appear, he can freely manipulate sound to his advantage. He's a student who turns out to be an old friend of JK's and wishes to reform their old band to become superstars.

* AnimeHair: His is all spiked up.* AntiVillain: Type IV. He's the least malevolent of any of the Zodiarts, and really just wants to play music rather than hurt anyone. He initially only fights because Fourze attacks him first. * CutLexLuthorACheck: He becomes Capricorn so he can further his music career.* DreadfulMusician: In human form, but not in Zodiarts form.* {{Foreshadowing}}: he was tasked by Gamou to find the Core Switch, and his powers apparently resonate with it. [[spoiler:And there's one student who was most affected by said power...]]* [[spoiler: LaserGuidedAmnesia: After being defeated by Fourze, his memory was wiped by Gamou.]]* MagicMusic: Can create Music Staffs to entrap his opponent, or entrance them.* MeaningfulName: "Goto" sounds like the Japanese pronunciation of "goat".** ShoutOutThemeNaming: And it's turned into his old nickname by shortening further till it's read roughly like GOD, antagonist organisation to Series/KamenRiderX - which JK was named for.* [[spoiler: MonsterOfTheWeek: Capricorn was treated similarly to Aries. Instead of being a general like Leo, Libra, and Virgo, he was just a MonsterOfTheWeek with backstory relevance for JK.]]* MusicalAssassin:** ThePowerOfRock** RockMeAsmodeus** SpoonyBard: His [[AllThereInTheManual Multi-Stringed Koto Uruk]] which is only used to blast a Musical Staff to ensnare his opponent. He doesn't use the music to brainwash his opponents (Ryusei notes that both he and Gentaro are immune to his song due to being shielded by Cosmic Energy) nor actually use it to his advantage (say, make the rave zombies to shield him so that the Riders can't touch him), and once Cosmic States captured the music he played, he had nothing left in his arsenal.*** It's this even outside of battle; when he plays his guitar the power of the Zodiarts Switches intensify. Moreover, the only reason he gets the power of Supernova was so that he [[spoiler: can use it to see whether or not Gamou can sense the power of the legendary Core Switch.]]* SquishyWizard: Like Aries above, he only uses his guitar as a means of attacking. Once Fourze ensnared him with his own music, he was done for.* WeUsedToBeFriends: With JK. [[spoiler: The end of #36 shows that they're hanging out again though.]]* [[spoiler: VillainousBreakdown: After seeing Gentaro both steal the show and turn JK against him, he really loses it. Though this may have something to do with the Supernova energy Gamou put in him.]]

!!Aquarius/Erin SudaThe Zodiarts representing the constellation Aquarius, the Water-Bearer. The eighth of the Horoscopes to appear, she is able to use Cosmic Energy to heal herself. Erin is revealed to want to pass the mock space exam to become an astronaut like her father and will ''not'' let anyone stand in her way...not even GenkiGirl and her rival, Yuki Jojima.

* TheAce: Transfer student from America who is smart, athletic and super-hot as JK puts it. This is even lampshaded with the letter A on her chest in regards with the exam.* AntiVillain: Another Type IV. Her first order of business as a Zodiarts was to heal Kengo, and she's only hostile to Gentaro because of his friendship with Yuki.** [[spoiler: After learning what really happened with the robot test, she does the SecretHandshake with Yuki and asks for a battle with Fourze. She then thanks Gentaro before Virgo retrieves her and erases her memory.]]* BookEnds: [[spoiler:Her last scene shows her "first" meeting with Gentaro and Yuki in front of the JAXA monument, just like when she was first introduced.]] * ButNotTooForeign* DarkChick: Apart from Virgo, she is the only Horoscopes that is obviously female in appearance.** [[spoiler: Now that we know who Virgo really is, it seems Aquarius and Scorpio are the only Dark Chicks around.]]* DeathGlare: Has this down to a fine art.* DistaffCounterpart: See below.* {{Expy}}: Let's see. SeriousBusiness about something? Check. Hates GenkiGirl Yuki but doesn't have qualms with anyone else? Check. Has a PetTheDog moment despite being a Zodiarts? Definitely. Gets talked to by Gentaro and immediately has a MyGodWhatHaveIDone moment shortly thereafter? Yep. Said MyGodWhatHaveIDone moment coincides with something in relation to Yuki Jojima? Uh-huh. She's pretty much the Horoscopes version of Motoyama (Perseus).* {{Foil}}: To Yuki. Where Yuki is hyperactive, loud and energetic, Erin is calm, quiet and still. Where Yuki believes in praying to the "Rocket Gods" and miracles, Erin believes in using skill to get what a person wants. Where Yuki tries to lift everyone spirits by being goofy, Erin tries to shut it down by being reasonable.* [[spoiler:GoOutWithASmile: After her fight with Fourze she gives one...and then Virgo teleports her to Gamou so her memory will be erased.]]* GreenEyedMonster: To make a long story short, she ''despises'' Yuki Jojima. More specifically, she hates Yuki Jojima due to the resemblance of a person who took her father's spot in going into space.* HairTriggerTemper: Anything that comes out of Yuki's mouth makes her panic and crazy; [[spoiler: she goes overboard when she assumes Yuki hid the camera parts for the team's robot to make her look bad--the keyword being "assumes".]]* HealingFactor: Her water jugs on her shoulders can heal anything...even a ''Cosmic States Limit Break''!* IGaveMyWord: She made a promise to Gentaro that she'd give a fair fight to Yuki during the exams.* [[spoiler:LaserGuidedAmnesia: Just like Goto prior, she has this too. However, the ending of #38 ends on a positive note with her excitably interacting with Gentaro and Yuki.]] * MakingASplash: Except her water gimmick acts as a HealingFactor, and she attacks with that nasty cat-o-nine-tails thingy.* {{Malaproper}}: She has a hard time pronouncing some Japanese sayings, such as proclaiming that she is "filthy" instead of "flawless" in Zodiarts form[[note]]Fuketsu = filthy, muketsu = flawless[[/note]]; that's how Gentaro figured out Erin was Aquarius. It even goes to the point that the '''Zodiarts''' have to correct her pronunciation. Justified in that she is foreigner and Japanese is damn hard to learn as a second language.* MeaningfulName: Her name is an anagram of Eridanus, a mythical Greek river that is somewhat associated with Aquarius.* [[spoiler: MonsterOfTheWeek: [[RuleOfThree Just like Capricorn and Aries]].]]* MyGodWhatHaveIDone: [[spoiler: Gentaro explains to Erin that Yuki did hide the camera parts because what she found in the box were instructions for the robot the team had to make. It was a SecretTestOfCharacter to see what the team could do under circumstances, and Yuki created that cat to make up for the loss. Gentaro notes that by being the leader, Yuki would be downright '''hated''' by everyone else, but she was willing to do so for the sake of the team. And when Erin returns after pushing Yuki off of the hill, Yuki states that she should leave the girl behind and save herself. Damn.]]* NotSoDifferent: Even though she won't admit it, she is actually similar to Yuki. Both wish to go to space, and both are determined to do the best of their abilities. It's just that their ways of leading (where Erin immediately takes charge and tells them what to do and Yuki just suggests something and presses on knowing that people will ''despise'' her for doing so) that are huge contrasts.* PetTheDog: The first thing she does as Aquarius? Use the water from her healing jugs to heal Kengo. [[spoiler:Unfortunately, not only does it NOT take, but in #45 [[YankTheDogsChain Kengo relapses worse than before]].]]** Despite being cold to Yuki, she also praises at how Gentaro and Kengo have the potential to become astronauts.* PoorCommunicationKills: [[spoiler: Because she was so angry at Yuki, she never got a chance to ask ''why'' Yuki hid the camera parts until Gentaro revealed that it was all a SecretTestOfCharacter.]]* SeriousBusiness: Going into space and passing the mock space exam is very important to her, since her father never had a chance to go. Thus while she is nice to Gentaro and Kengo, she ''utterly'' despises Yuki because she doesn't believe the GenkiGirl is taking the whole thing seriously.* SpellMyNameWithAnS: In Japanese, it's spelled as エリーヌ (long ''i'' sound, ends with ''nu''), rather than the usual エリン (short ''i'' sound, ends with ''n'').* StoneWall: That HealingFactor of hers makes it near impossible for her to be defeated. But if you can destroy both the water jars on her shoulders at once (even one jar is enough to heal the other), she's done for.* VisualPun: Aquarius is the water carrier. So naturally, [[spoiler:she's got a great big pair of jugs, as in the jugs on her ''shoulders''.]]* WhipItGood: [[AllThereInTheManual The Nectar]]. Which has multiple heads.* WorthyOpponent: Considers Kengo and Gentaro these in the astronomy exam. Yuki, on the other hand, is the exact opposite.

!!Taurus/Yuuta Sugiura

The ninth member of the Horoscopes to appear, he is based off of Taurus, the Bull. He was present for the mock space exam, though he was later revealed to have the potential to become Taurus. An avid golf player, who forces people to sign contracts with him, and the loser is banned from interfering with the winner in any way. Seeing himself as a force that should not be defied, he has starting changing the rules at AGHS, forcing those who do not comply by contract.

* TheAce: In addition to being one of the four to make it into the school space program, he also bests JK and Gentaro in their specialties of break-dancing and double dutch. Considering that he explicitly ''breaks the rules of physics'' during the competitions, it's logical to assume that the switch is helping him out somehow.* [[spoiler:AndIMustScream: Unlike Capricorn and Aquarius, he got shucked into the Dark Nebula. ''While in Zodiarts form!'']]* BeatThemAtTheirOwnGame: What he did to Gentaro and JK.* CharacterTics: Always playing mini-golf in his office. * ChekhovsGunman: At first, he seems to have just been there for the exam. At the end of the episode, though, Libra reveals that Sugiura is going to be Taurus.* DealWithTheDevil: Seems to be his MO when dealing with potential threats.* [[spoiler:EvenEvilHasLovedOnes: Apparently, he has a crush on the former student council president, and that is the real reason why he has gone so far off the deep end.]]* {{Expy}}: Of Yamada, the Aries Zodiarts. Both of them are control freaks that suffer from god complexes and use their newfound power to rule their school with an iron fist.* EyepatchOfPower: He has one in his Zodiarts form. Note: it's on his right.* AGodAmI: Thanks to Hayami's manipulation, Sugiura has gained a god complex.* [[HeWhoFightsMonsters He Who Fights Rule Breakers]]* [[spoiler:HeelFaceDoorSlam]]* KickTheSonOfABitch: His first four victims ''really'' deserved it.* LightningBruiser* ALoadOfBull* MeaningfulName: The syllables in his name can be rearranged into "Taurusu Gyu" (Gyu meaning "bull").* MundaneUtility: Gu-anna, the medium of his MindControl powers, and also an excellent ''golf club''.* MyGodWhatHaveIDone: [[spoiler: When confronted with the former School President, he finds that he can't actually steal her soul when he finds out she's deliberately breaking rules--wearing mismatched socks, uniform and having a barbecue on the school roof--and cries.]]* MindControl: Not only does signing his contract make people lose all body function, but thanks to his [[AllThereInTheManual Gu-anna]], he can suck out their souls and put them under his control. He even goes as far as to [[spoiler: '''''brainwash Meteor'''''!]]* ANaziByAnyOtherName: The mannerisms of his disciplinary committee should give you a clue.** However, this is because Sugiura had sucked out their souls beforehand.* [[spoiler:SixthRangerTraitor: Also like Aries, he has this role amongst the Horoscopes. While Aries didn't so much as betray them as he did just utterly screw around instead of doing anything productive, Taurus actually left the Horoscopes all together.]]* SoreLoser* StaffOfAuthority: His [[AllThereInTheManual Gu-anna]].* TyrantTakesTheHelm: Has started using his new found powers as a Horoscopes to severely limit the individuality of AGHS (Which is ironically the exact opposite of what Gamou wants) by enforcing new rules on the school, including a new dress code.

The tenth Zodiarts to appear representing the constellation Gemini, the Twins.[[spoiler: A dark aspect of Yuuki that was created when Libra and Leo forced her to use a Switch that separated their body. Due to this, both Dark and Light aspects have a 24 hour time limit to see which side will be the dominant side, while the other one fades away.]]

* [[spoiler: ActionBomb]]* BreadEggsMilkSquick: The pranks Gemini pulls on the Kamen Rider Club: tying up Ohsugi's suspenders to stretch it to its limit, spraying JK with a water hose, dumping flour on Shun, and finally, throwing Miu off a balcony.* DarkChick: Truly embodies this trope compared to Aquarius and even Virgo.* DeathDealer: Wields exploding cards called, respectively, [[AllThereintheManual Lynceus]] the red cards and [[AllThereintheManual Idas]] the blue cards as weapons.* DoppelgangerAttack: Like its name suggests, it can make a duplicate of itself as it's Supernova ability, [[spoiler: that explodes]].* EvilLaugh** AsideGlance: and she glances at the camera when she does it. ''Twice''.* {{Expy}}: Design-wise, she looks like [[Series/KamenRiderDouble Nasca]]. In personality, [[Franchise/{{Batman}} Harley Quinn]].* GenkiGirl: A villainous example.* GlassCannon* HavingABlast: Uses cards that explode. Red ones instantly explode, Blue ones act similar to the Stamper Switch.* TheHyena* MeaningfulName: [[spoiler:An alternate spelling of Yuuki Joujima in English (with a lot of liberties taken) is "Yuuki Jousima", which can be rearranged to say "I am Soujikyuu"]]; "Soujikyuu" is the name of the Gemini astrological sign (not the constellation, which is Futago-za) in Japanese.* ThePrankster* PsychopathicManchild* StealthPun: a ''double''-themed character whose secondary motif is a jester; a ''joker''. [[Series/KamenRiderDouble Don't get it?]] * VillainousBreakdown: [[spoiler: Gets one when Gentaro shows Yuuki her homemade Space Ticket and thus frees regular Yuuki from fading away.]]* VillainousHarlequin[=/=]TheJester* WhiteMaskOfDoom: [[spoiler: As Dark Yuuki...until spending enough time active causes her to occupy the real Yuuki's presence, represented by her ''acquiring the real Yuuki's face while forcing said White Mask onto her instead!'']]

!!Pisces/[[spoiler:Ran Kuroki]]

The eleventh and final Zodiarts that represents Pisces, the Fish. [[spoiler: Ran Kuroki is a former school swimmer freshmen who was first mistrusting of her older classmates after an incident in the past, but changed her behavior after helping Gentaro save her friend Haru from being a Zodiarts; who she now regularly visits in the hospital. Was forced/willingly chose to use the Switch to save Hayami from Leo]].

* ApocalypseMaiden: [[spoiler:As the last Horoscope, the Club now has to protect her as well as her Horoscope Switch. If what Libra said is true, failure will result in the destruction of Japan.]]* DarkChick: [[spoiler:Defied.]]* EmpoweredBadassNormal: [[spoiler:Ran was a great swimmer and competent fighter even before becoming a Zodiarts, and managed to hold her own against Leo even after first transforming.]]* LightningBruiser: Her underground swimming abilities allow her to move quite fast, and she is capable of matching [[spoiler:Leo]] in a fight. * MakingASplash: Not used offensively, yet, but she can "swim" underground, as shown when fighting [[spoiler:Leo]].* MeaningfulName: In the only other stretch of the group, when literally translating her name into English, you get "unbarked lumber" for "''kuroki''" and "orchid" for "''ran''", which form the (again a stretch) acronym UO which is the Japanese word for fish, which is what Pisces is represented by.* NiceJobBreakingItHero: [[spoiler:It turns out that Libra and Leo were banking on Ran to transform and save the former from the latter, therefore ''bringing the last Horoscopes switch into existence'']].* OurMermaidsAreDifferent* ProngsOfPoseidon: Type-1. Promos for the movie show it with one. However, it hasn't appeared in the show itself yet. * TokenGoodTeammate: [[spoiler:Pressed her switch for entirely selfless reasons, and by far beats Capricorn, Taurus and Aquarius eventually for the position of least malevolent Zodiarts.]][[/folder]]

A member of the football club who, fed up with his peers' poor treatment of him, accepts the Orion Switch to get revenge. His patron constellation is [[ExactlyWhatItSaysOnTheTin Orion]] the Hunter.

* CameraFiend: His family owns a photography studio. At the end of Episode 14, he quits the Football team and joins the Photography Club.* CarryABigStick: [[AllThereintheManual The Lemnos Club]] in Last One* ColdTurkeysAreEverywhere: [[spoiler:The real reason why he's not going back to school.]]** [[spoiler:At the end of Episode 14, he's recovered thanks to Gentaro giving Miura all the photos Mari took of him.]]* DefeatMeansFriendship: Gentaro extends his hand of friendship to him. [[spoiler:However, his promise of friendship isn't enough to stop Miura's withdrawal symptoms from the Switch. Fortunately, at the end of Episode 14, he takes Gentaro's hand of friendship for good.]]* TheDogBitesBack: The part of his FreudianExcuse for accepting the power of Orion. Doesn't help that it wasn't intentional on Shun's part.* EmbarrassingOldPhoto: Inverted. He and his family take photos of young children in a studio they own.* LuckilyMyShieldWillProtectMe: [[AllThereintheManual Chios Shield]] in Last One.%%* MightyGlacier: Large, imposing, and powerful. Pretty much made to beat the ever-loving crap out of people.* NoRespectGuy: Gets told by Shun that he's going to be benched rather harshly. In Episode 8, Shun confesses this was due to his father telling him to do so, and he felt remorse when he saw how this took a toll in Miura's sanity.* ThePowerOfLove: [[spoiler:His love for Mari helps him overcome his addiction to the Orion Switch.]]

!!Tamae Sakuma/Chameleon->Live Actor: Maria Yoshikawa

A third-year and member of Miu's cheerleading trio, whose disillusionment with Miu's two-year winning streak at the Queen Festival drove her into accepting the Chameleon Switch. Her patron constellation is Chamaeleon the Chameleon.

* TheCheerleader* EasilyForgiven: Miu forgives her for becoming Chameleon, and hopes to see her work hard when they run for the Queen Festival next year.* GreenEyedMonster* {{Invisibility}}* JackOfAllStats: The stretchy tongue and invisibility give her a better edge than most Zodiarts, but not enough to outmatch Fourze's arsenal.* OverlyLongTongue* ShoutOutThemeNaming: To the Tama siblings and Ken Sakuma, characters in ''Series/KamenRiderV3''.* TheStarscream* VillainessesWantHeroes: When she returns, it turns out she wants to ask Gentaro to the prom.* WhipItGood: With her tongue.

!!Fumihiro Nitta/Unicorn->Live Actor: Kiyotaka Uji

A first-year fencer who holds a deep grudge against JK for once using him as a human shield against a bunch of bullies, severely injuring his right arm and thus preventing him from competing in a fencing meet. Driven by vengeance, he accepts the Unicorn Switch. His patron constellation is Monoceros the Unicorn.

* CoolSword: [[AllThereintheManual Longsword Monarch]].* FalseFriend: JK pretends to be friends with Nitta so that he can use him.* GameBreakingInjury: Thanks to JK using him as a HumanShield, he got a bad injury on his right arm and thus was forced to miss out on a fencing tournament. This, coupled with him overhearing that he was simply used, fuels his hatred against JK. It's ultimately subverted as he's not only recovered, but well enough to augment the power of his Switch.* HumanShield: What JK made him to be in the past against a bunch of bullies. This fuels his rage against him.* LightningBruiser: Hard to hit, pretty speedy, and the rapier is pretty useful when regular attacks won't cut it.* MasterSwordsman: Justified - the Switch evolved in reaction to his training in fencing.* {{Unicorn}}: [[ExactlyWhatItSaysOnTheTin Obviously.]]

!!Teruhiko Satake/Hound ->Live Actor: Ryuji Sato

A second-year and son of the notoriously ruthless detention teacher, Takashi, who has decided to rebel against his strict father. Along the way he receives the Hound Switch, and soon goes on a rampage. His patron constellation is Canes Venatici, the Hunting Dogs.

* BlackSheep* BladeBelowTheShoulder* ChainPain: Both in human form (only for the symbolism though) and Zodiarts form.* FreudianExcuse: Conveniently mirroring Shun during Episodes 7-8.* JackOfAllStats: His two attacks are great for long and mid-range opponents. Unfortunately, most of the time he is able to escape due to something else happening (ie Scorpio helping him or Shun stopping Fourze from defeating him). Once Fourze had him in the open, he was done.* JapaneseDelinquents: At home, anyway.* LivingADoubleLife: JK's intel reveals that at school he plays TheDutifulSon and student; after school, however, he became a petty thief stealing chain-like jewelry, using them as his weapons and also to symbolize his desire to break free from his father's shadow.* NotSoDifferent: He and Shun both have overbearing fathers; they only differ in actions - whereas Shun was driven into a breakdown but eventually found friends, Teruhiko decided to bust the chains out and act like a rebel.* SpikesOfVillainy** SpikeShooter

!!Ritsuko Usaka/Altar ->Live actor: Hikari Kajiwara

A leader of a witches' coven that comprises Yuri Kuramochi, Masami Okamura and herself. As Altar she uses her powers to make it appear that her group has magical powers. Her patron constellation is Ara the Altar.

* BrokenPedestal: For Tomoko.%%* EvilCripple: A hunchback in Zodiarts form.* FreudianExcuse: Reveals that she's already sick of being ostracized because she can see things others couldn't, and getting blamed by teachers for any supernatural mishap she witnesses.%%* [[FlamingHair Flaming]] PrehensileHair%%* {{Goth}}* HoistByHisOwnPetard: Tries to beat Fourze using her head of fire...but his Fire States makes him able to ''absorb'' her attacks, thus rendering them useless.* NotSoDifferent: With Tomoko - both have ESP, as shown in a flashback when they first meet, as both of them reach for the same book. [[DramaticIrony The glaring difference between their fates]] gets lampshaded below.* MagicStaff: [[AllThereInTheManual Aradia Staff]] which produce fire and have psychokinetic ability.* MightyGlacier: Doesn't move a lot and uses her levitation to get an advantage on her opponents. Her fire attacks are very powerful though...until Fourze absorbed it and sent it back at her.%%* MindOverMatter* PetTheDog: Despite her hatred of teachers, she liked Sonoda-sensei enough to be honest about how her presence could've saved her from the life of a witch and exhorts her to run away before she blows up the entire school. [[spoiler: Becomes very hard to look at when you find out about what Sonada really is 3 episodes later.]]%%* PlayingWithFire%%* PsychicPowers: Claims joining the witches coven with give you them. [[spoiler:She lied]].%%* SkunkStripe: Has a streak of blonde hair.* ThenLetMeBeEvil: Being treated like a freak and always being blamed for the supernatural occurences only she can see caused her to turn bad for real. She actually quotes this almost word for word.* VillainessesWantHeroes: When she returns, it turns out she wants to ask Gentaro to the prom. [[spoiler: She had to settle with Ryusei instead in #26.]]* WickedWitch: Or so the Altar Zodiarts' power allows her to.

!!Hiroki Makise/Pyxis ->Live Actor: Takafumi Shinohara

Yuki's former "friend" at the Astronomy Club who has a massive crush on her. Uses his Zodiarts power as a way to get to her and then extract his revenge. His patron constellation is [[ExactlyWhatItSaysOnTheTin Pyxis]] the Mariner's Compass.

* {{Adorkable}}: Averted. He's a geeky dork with glasses, but he's also a psycho who could kill anyone and stalk any girl he wanted.* BewareTheSillyOnes: No, really. Makise went from geeky self-absorbed dork with a crush on one girl, play-acting as the "rest" of the astronomy club [[WesternAnimation/MyLittlePonyFriendshipIsMagic "Party of One"]]-style, to invoking a DealWithTheDevil with Yuki, turning Fourze's attacks on his friends and finally attempting to ''SHOVE A [[BusFullOfInnocents BUS FULL OF STUDENTS OFF A BRIDGE.]]'' [[ArsonMurderAndJaywalking And all within the sophomore year!]]** There's also the fact that he's a complete weakling in hand-to-hand combat, the only blows he ever manages to score on Fourze being a result of pretty much just flailing his bladed arms around like a dork, but his power of being able to move things with his mind make him a threat.* BladeBelowTheShoulder: Averted. Despite the way they are place and look, Pyxis does not use them for offense.* [[spoiler:TheBusCameBack: He comes back in #37.]]* CharacterTic: Has a peculiar way of holding his switch, by sticking out his index finger as though he were pointing before clicking on the switch with his thumb, often holding his hand sideways as he does this. [[spoiler:He holds the Radar switch like this in the movie when he switches it on.]]* DirtyCoward* DowsingDevice: How the blades on his arms function. They range from having the ability to find something (by letting someone touch them and think about the item in general), or using them to ''control'' people for his own use.* ExplainingYourPowerToTheEnemy: He was smart enough to AVERT this; [[spoiler:Fourze tried firing his Launcher missiles at Pyxis, not knowing of the latter's powers until it was too late, destroying what seemed to be the locker to the Rabbit Hatch in the process.]]* FailedASpotCheck: [[spoiler: Yuki never even realized he was also participating in the test until they were all inside the Isolation Chamber. Naturally, she freaks out and backs away from him.]]* FourEyesZeroSoul: Was obsessed with Yuki for quite some time, but now that he's Pyxis he decides that it's time to crush her like (he thinks) she did to him, stating she was damaged goods. He's also the first Zodiarts to be portrayed as an unsympathetic {{Jerkass}} from the get go.** What's more, he was like this ''before'' Scorpion gave him that switch!* HeManWomanHater: His stalker-like tendencies fueled this ideal. Tomoko lampshades this [[spoiler: when he returns in #37--25 episodes later]] by saying, "Simply, he's a misogynist."* ILied: Made a deal with Yuki to find the locker if she agreed to be his girlfriend and abandon her friends. He had no intention of keeping his side of the deal and instead blew up the locker so he could see her cry.* {{Jerkass}}: So much so that [[spoiler:Gentaro doesn't extend his hand of friendship as he'd done with previous Zodiarts]].* KickTheDog: Only helped Yuki find the locker for the Rabbit Hatch just so he could destroy it and make her cry.* KnightOfCerebus: Of the Monster-Of-The-Week variety.* LaserGuidedKarma: [[spoiler:Becomes the first Switcher to miss out on Gentaro's friendship offer, leaving him instead to try to flee (in vain) from the girls whom he trapped on the bus at the end of Episode 12.]]* LonersAreFreaks: He's the only member of the Astronomy Club (Yuki notes that it's because of his behavior that everyone left), and is shown to interact with no one else in the school. Oh and he's a stalker, that should explain everything.* [[WomanScorned Man Scorned]]: Yuki has no feelings for him whatsoever, so he made it his duty to crush her by ''trying'' to destroy the locker connecting to the Rabbit Hatch. Taken UpToEleven in Episode 12 when [[spoiler:he tries to murder every other girl who shot him down by trapping them on a bus bound to drive off an unfinished bridge]].* MindOverMatter: Can control objects [[spoiler: and people]] with the blades on his arms.* NeverMyFault: Seems completely oblivious to the fact Yuki isn't turning him down out of spite but out of repulsion over his [[StalkerWithACrush creepy obsession with her]], instead deciding that she deserves to suffer for it. This extends to the 20-30 other girls that have rejected him.** He also claims it's Fourze's fault for (apparently) destroying the locker to the Rabbit Hatch (when in fact he redirected Fourze's missiles).* PsychopathicManchild: Let's see, a loony kid who obsesses over Yuki but then tries to destroy her once it became clear that she's not going to reciprocate his "feelings" and takes ''sheer delight'' in [[spoiler:turning girls into shooting stars by ''killing them'' (as evidenced by a future diary full of cute pictures depicting his gambit to send a bus full of them crashing off of an unfinished bridge)]]? Oh, yes. And JK's intel implies he's been like this ''way before'' he even got his Switch!* [[spoiler:ReformedButRejected: Only in his own mind. (re: #37)]]** [[spoiler:Played straight in the movie, though, when he is chosen among the 40 people who will press the astro switches in order to create a new power to save Gentaro and Ryusei.]] * SlasherSmile: Has one of these whenever he's about to transform into Pyxis.* SquishyWizard: He terrorizes Amanogawa with his telekinetic powers. The Zodiarts Switches' ability to mutate to suit [[PersonalityPowers their users' natural talents]], however, leaves him in a bad spot. Whereas Miura was a football player, Sakuma a cheerleader, Nitta a fencer, Satake a brawler, and Usaka a firm believer in black magic, he's nothing but a geeky dork with serious psychological problems, leaving him an ''utter'' pushover in melee combat (one exploited by Fourze's mid-range-oriented Elek States).* StalkerShrine: He wasn't only obsessed with Yuki. JK found out that the guy has a star map with the names and pictures of all the pretty girls in Amanogawa [[spoiler:that he was gong to put on a bus and make it crash off of an ''unfinished highway'']].* StalkerWithACrush: For Yuki. He's given her incredible amounts of letters, gifts, emails and voicemails for God knows how long.** [[spoiler:Apparently extends to a host of other girls whom he forced onto a bus headed for an unfinished bridge.]]* TeensAreMonsters: He's the worst out of all of the [[spoiler: unevolved]] Zodiarts shown ''and that's saying something!''* VileVillainSaccharineShow: In a rather lighthearted series where even [[BigBad Gamou]] [[WellIntentionedExtremist seems to have good intentions]] and every other Zodiarts is an AntiVillain, a genuinely creepy [[TheSociopath sociopath]] like this guy ''really'' stands out.

!!Soushi Motoyama/Perseus ->Live Actor: Ryutarou AkimotoPresident of the Art Club. He takes the Perseus Switch so he can dish out some punishment upon anyone (and anything) that disturbs his work. His patron constellation is [[ExactlyWhatItSaysOnTheTin Perseus]].

* AxCrazy: He was the second craziest Zodiarts next to Makise, but he's shown to be much better off at the end of Episode 16.* BerserkButton: This guy ''really'' hates Yuki's voice when she sings, but has no problem with Abe and the rest of the Glee Club.** He also hated Gentaro singing the Hayabusa song (although Gentaro might've done it deliberately to lure him out)* ChildhoodFriends: Abe mentions that they went to Elementary and Middle School together. At the end of #16, they're on the rooftop shaking hands.* DisproportionateRetribution: He's decided to turn everyone who kept him from painting in peace into ''stone statues''. His victims are three punks who bullied him, a pitcher who accidentally knocked over some paint cans with a stray baseball, and two GossipyHens who, in his opinion, won't shut up. And that's not yet mentioning a building he damaged such that it will lean, because ''it was blocking his view of Mount Fuji''.* FreudianExcuse: Because everyone's been bugging him and not letting him paint in peace, he's become a Zodiarts to shut them up for good.* HairTriggerTemper: If you do ''anything'' to interrupt his painting, he'll go berserk.* [[spoiler:HeelFaceDoorSlam: the first Zodiarts in the series to show redemption even in Last One stage, but Libra uses MindControl on him to force him to fight Fourze.]]* {{Irony}}: His powers get blocked when Gentaro uses the [[ThePenIsMightier Pen Switch]] on him and splatters ink on his Medusa Hand.** Well it has been said that the pen is mightier than the sword.* MadArtist: His art is decent, but his obsession to his works is...[[SeriousBusiness unhealthy, to say the least]].** He gets much better at the end of #16, deciding to redo his Mount Fuji picture and is shown to be more calm about it.* ManlyTears: Breaks down into these (While in Zodiarts form, mind you) once he sees the works of the kindergarten class surrounding a previous work of his, and realizing that he was only trying to make ''himself'' happy with trying to perfect his painting.* MasterOfNone: Sure he has the sword and petrification powers, but he's nothing when they're rendered useless.* {{Medusa}}: His left hand turns people to stone. And if [[spoiler:[[AndIMustScream Gentaro was conscious the whole time...]].]]** Kengo notes that [[spoiler: the petrification wasn't complete and that's why Gentaro was able to move around despite becoming stone. Still, doesn't necessarily mean the other victims aren't somehow conscious despite being unable to move.]]* MyGodWhatHaveIDone: Upon arriving at the kindergarten class, he's awed that his previous painting is surrounded by all of the other works of the kids, reminding him of Gentaro's drawing of Mount Fuji. He then realizes that he had taken his art so seriously that he forgot the ''reason'' he'd been making it in the first place, to make the children happy, breaking down into tears. [[spoiler:It's also implied that this canceled out his ability to evolve into a Horoscope.]]* PetTheDog: Yes, he's [[AxCrazy utterly crazy]] and has [[HairTriggerTemper bad anger issues]], but the reason he wants to perfect his paintings is because he simply wanted to make a kindergarten class he sometimes visits happy with his works.** Also, he doesn't hate all of the Glee Club; his ire is just toward Yuki and her Hayabusa song. As shown in the end of #16, he's back to being good friends with Abe.* SeriousBusiness: [[MundaneMadeAwesome Painting]]* SecretHandshake: Shown twice; he does it with Gentaro (as Perseus) and then once more with Abe at the end.* SuperOCD: He proclaims that anything that isn't perfect must be destroyed. Fortunately, he sees all of the kindergartners' drawings next to his old painting for them, and realizes that it doesn't matter if it's perfect or not. What mattered was the passion and love they put into them.* TakenForGranite: What frequently happens to his victims.

!!Kimio Nonomura/Lynx ->Live Actor: Shohei YamazakiKengo's self-proclaimed rival, who was given his Switch by Libra. He uses it in order to get rid of the competition of all students with higher test scores than he. His patron constellation is [[ExactlyWhatItSaysOnTheTin Lynx the Lynx]].

* CharacterTics: Snapping his left thumb and index finger, which quickly outed his true identity to the Club.* FlatCharacter: Aside from having a one-sided rivalry with Kengo on the smartest student in school, there's nothing else on him. Even more so since we don't even see him after Gentaro destroys his Zodiarts switch.* FragileSpeedster: Uses his speed to his advantage, but can't take powerful hits.* PantheraAwesome* SeriousBusiness: He knocks out the competition for smartest student in the school.* ShadowArchetype: He's basically Kengo minus the idea of him wanting to make friends and the toleration for Gentaro's antics.* SmallNameBigEgo: It comes with being Kengo's "self-proclaimed" rival.* TheRival: Claims to be this for Kengo.* WhatHappenedToTheMouse: He was last seen in the Rabbit Hutch with the KRC suggesting to put him in a storage closet. We don't even know whether or not he changed for the better.* WolverineClaws: Comes in hand with his feline theme.

!!Jin Nomoto/Dragon ->Live Actor: Ryu AndoCaptain of the Track and Field team who became a Zodiarts to discourage outside help and to kill the Kamen Riders, starting to grow bored of track practice. His patron constellation happens to be Draco the Dragon.

* FeedItWithFire: And Electric, too!* ForTheEvulz: Why he went about and became a Zodiarts.* ImprovisedWeapon: Throws shot puts around. Surprisingly, nobody picked up on this and said "Maybe the Zodiarts is part of the track and field club!"** To be fair, they were already having trouble with Kengo and Gentaro's relationship to actually pay attention.* JerkJock: To a degree that makes even pre-CharacterDevelopment Shun look like a ''NiceGuy'' in comparison.* MadeOfIron: More like made of ''steel''...[[DeathByIrony Which spelled the end of his Zodiarts career when Fourze obtained Magnet States]].%%* MightyGlacier: He can also strike back really hard.* NighInvulnerable: It can stand the attacks from both Fire and Elec states, and Meteor can't even land a single blow on it! The "Nigh" comes into play when Fourze assumed Magnet States, [[WeaksauceWeakness then mopped the floor with Jin]].* NoSocialSkills: Shun notes that Jin's "not good with words" when he returns, implying this played into Jin's Zodiart stint.%%* OurDragonsAreDifferent* PlayingWithFire: In Episode 20, he gains the ability to shoot fire.* ShoutOut: A dragon that goes arround throwing balls. The reference would only be clearer if he [[DragonBall granted wishes]].* TookALevelInKindness: He's still kind of a prick, but he's cooled off considerably when he appears in #25 and #26. He's even ''disappointed'' when Gentaro briefly doubts [[NotMeThisTime Ritsuko's still good]].* VocalDissonance: The some what squeaky voice that comes off the fearsome looking suit might be surprising.

!!Natsuji Kijima/Pegasus ->Live Actor: Soran TamotoA Zodiarts who is attacking talented martial artists to test its own strength. Its patron constellation is Pegasus [[spoiler:until he evolves into Cancer]].

* BeneathTheMask: A very jolly fellow who sprinkles [[PurpleProse rakugo phrases and puns]] into his normal speech. [[spoiler:Then after he is uncovered as Pegasus, he drops the flowery speech and becomes sinister and cold.]]* BloodKnight* CharacterTic: Clops his feet like a horse when about to throw a high kick. [[spoiler:He only does this in order to incriminate Haruka Utsugi, and drops it once he is uncovered.]]** Nowadays he's more often seen tapping that fan of his in time with the dialogue.* DisproportionateRetribution: Part of the reason why he [[spoiler:framed Haruka Utsugi was because she '''took away his fan''' when he accidentally hit her with it]], though he admits he would've done it to ''someone'' anyway and that was just why he did it the way he did.* FauxAffablyEvil* ForTheEvulz: Outright admits most of his reason for becoming a Zodiarts and [[spoiler:framing Haruka]] was simply because he enjoyed it. [[spoiler:Pretty much becomes his modus operandi when handing out Zodiarts Switches.]]* {{Frameup}}: [[spoiler:Tries to frame Utsugi by mimicking her fighting style, dropping some evidence and telling the KRC that she took it from him, and outright saying "Do you really want to hit your teacher?" when Gentaro fights him in Episode 21.]]* FromNobodyToNightmare: Found his switch by ''complete accident'' (rather than being selected by the Horoscopes) and still manages to be [[spoiler: the first MonsterOfTheWeek to evolve into a full blown Horoscope.]]* MeaningfulName: [[spoiler: His given name can be alternately read as the word for "crab".]]* [[spoiler:OneWingedAngel: Transforms into Cancer.]]* {{Pegasus}}: Self explanatory.* PungeonMaster: A member of the school's [[http://en.wikipedia.org/wiki/Rakugo Rakugo]] Club, he often mixes puns and wordplay into his speech.** Especially obvious [[spoiler:in Episode 27, when he spends a couple of minutes during his fight with Meteor making puns about fish and tadpoles, to Meteor's growing annoyance.]]* RedHerring: Was thought to be Haruka. [[spoiler:He was deliberately impersonating her fighting style to set her up as said Zodiarts out of petty revenge for confiscating his fan, and ForTheEvulz.]]* ShadowArchetype: He's pretty much Ryusei without something to keep him good - both put up a NiceGuy facade to hide their more serious personae. [[spoiler:Whereas Ryusei ultimately TookALevelInKindness, Natsuji is rapidly JumpingOffTheSlipperySlope and into a full Horoscopes.]]* TheSociopath: What he's like BeneathTheMask.* WickedCultured* WingsDoNothing: They're just there for decoration.

!!Norio Eguchi/Cygnus->Live Actor: Shugo Nagashima->Voice Actor: Taiki MatsunoA student who wishes to be a hero after observing Fourze. He becomes a Zodiarts who styles itself as a Hero of Justice, complete with flashy entrance and catchphrase. However, it possesses a fragile ego and spitefully assaults anyone who slights it [[spoiler: and even more so]]. Its patron constellation is Cygnus the Swan.

* BitchInSheepsClothing: [[ZigzaggedTrope Zig-zagged]]. At first it seems like a hero for justice...until JK reveals that Cygnus beats people up who make fun of it. [[spoiler:Misa Toriizaki was the suspect, but when it turned out to be Eguchi, he was revealed to have a split personality, where his darker side was the one beating people up including (mentally) Eguchi for not living up to his standards. By the time he resisted going the Last One Stage, however, he get abducted and the previous RedHerring lead her group into forcing him to transform!]]* CaptainErsatz: Of both [[Series/KamenRiderDenO Sieg]] and [[Series/KamenRiderKiva Kamen Rider IXA]].* CharacterTics: Assigning people points based off of good or bad actions; Cygnus fangirl Misa Toriizaki does the same [[spoiler:but this is just a RedHerring]].* {{Cosplay}}: Has an outfit inspired by Cygnus, [[spoiler:and then dons one based on Fourze at the end]].* DirtyCoward: The darker personality used Tomoko as a shield to keep Meteor from bashing him in. He does it again in Episode 24, this time with [[spoiler:[[LaserGuidedKarma Toriizaki]]]].* EveryoneCallsHimBarkeep: Due to his reputation as a hero, everyone simply calls him "Cygnus"; Gentaro's fight with his Last One state in Episode 24 marks the first time anyone refers to him as the Cygnus Zodiarts.* FeatherFlechettes* {{Fanboy}}: Wanted to become a hero after observing Fourze fighting off Lynx in Episode 18 then switched to Cygnus after he was saved from thugs. [[spoiler:He decides to go back to worshiping Fourze via dressing up like him and helping a lady on the street.]]* GlassCannon: Can beat up people with a fight and uses his feathers as projectiles, but once Meteor gives him a good kick, he goes down.* LadyMacbeth: Became a victim of one, by Toriizaki just as his switch reached the Last One Stage.* PaintItBlack: His PerpetualMolt does this [[spoiler:once he triggers Last One.]]* PerpetualMolt: The indication that Cygnus has arrived.* SecretTestOfCharacter: Gentaro gets the members of the KRC to dress up and act out in situations to let Eguchi help them out. Eguchi settles on helping the little school kid (aka Yuki) get her balloon back.* [[spoiler:SplitPersonality: The first time Eguchi used the Zodiarts Switch, it caused the darker side of his personality taking control of Cygnus while the real guy remained oblivious.]]

!!Yayoi Tokuda/Coma ->Live Actress: Kasumi SuzukiA third-year who is head of the Newspaper Club. She becomes a Zodiarts who uses its hair to create copies of the Chameleon, Altar and Dragon Zodiarts in order to frame their original Switchers and prevent them from graduating. Its patron constellation is [[http://en.wikipedia.org/wiki/Coma_Berenices Coma Berenices]], the hair of [[http://en.wikipedia.org/wiki/Berenice_II_of_Egypt Queen Berenice II of Egypt]].

* BitchInSheepsClothing: Seems to be a reasonable reporter...then she intentionally frames Tamae, Kimio and Ritsuko of wrongs they never committed - all because ''she doesn't want to graduate and neither will she let the others do so''.* CameraFiend* ClubPresident: Of the Newspaper Club.* TheFaceless* {{Foreshadowing}}: What's she doing in her first appearance? Trying to get an article out of Tamae, Ritsuko ''and'' Jin, even though it's ''only'' Ritsuko's alter-ego who "returned" around that time.* FourEyesZeroSoul%%%%%%%%%%%%% "To a frightening degree." is not context%%%%%%%%* GirlishPigtails: * GrowingUpSucks: Her motivation for becoming a Zodiarts and framing Ritsuko, Kimio and Tamae? She doesn't want to leave high school, and feels that neither should everybody else.* {{Hypocrite}}: Becomes a monster because she loves AGHS and doesn't want to graduate. Yet she furiously claims Tamae, Jin, and Ritsuko don't ''deserve'' to leave after their actions as Zodiarts, apparently seeing AGHS as a punishment as well.* InformedAbility: JK claims that she makes for a better KnowledgeBroker than him. At the very least, she was able to figure the identities of former monsters.* MookMaker: Can turn its hair into copies of existing Zodiarts.* NotSoDifferent: To Miu. Both are seniors, presidents of their respective clubs, and dread graduating. However, this is where similarities end: whereas Miu learns to accept the fact but Yayoi refuses to accept it.* PrehensileHair* SquishyWizard: She can create clones from her hair and use it to entrap opponents, but once she's rendered immobile by the Power Dizer, she's pretty much good as done.* StringyHairedGhostGirl: Provides the inspiration for this Zodiarts. Not just for the stringy hair and deliberately creepy LimpAndLivid portrayal, but Yayoi also harbors a grudge.* WhatHappenedToTheMouse: We don't know if she even graduates or gets held back like she wanted to.

!!Haru Kusao/Musca ->Live Actor: Jigen ArakiA freshman who was given his Switch by Libra in an attempt to be more outgoing. His patron constellation is Musca, the Fly.

* BerserkButton: Due to the Switch, he lashes out at Ran on her insistence on always trying to protect him [[spoiler: or whenever she utters her CatchPhrase "I'll protect you Haru!"]].* BigCreepyCrawlies* DetachmentCombat: Can separate into a [[TheWormThatWalks swarm of flies]] to annoy Fourze.* DullEyesOfUnhappiness: Has serious bags under his eyes as he uses the Switch more and more.* HowDoIShotWeb: A rare villainous example. Not only is he a first time Switcher still getting used to his new form, his Switch is evolving, continually dumping new powers on him.* IJustWantToBeBadass* InASingleBound: His initial power.* LethalJokeCharacter: Considering that he starts out as a wimp, and gets a simplistic Zodiarts design that's little more than a glorified {{Mook}} with a pathetic ''housefly'' AnimalMotif, his sudden rush of powers really comes out of nowhere.* OnlyFriend: Ran is his only friend even though he actually wants to be friends with Gentaro. Ran is pretty much the sole '''reason''' that Haru even became a Zodiarts in the first place [[spoiler: and ironically the reason that he gets worse.]]* [[spoiler:PowerGivesYouWings]]: Once he reach Last One.* {{Protectorate}}: Deconstructed in that his desire to change is ousted by his overprotective friend, frustrating him.* ShrinkingViolet: Doesn't help that he has a pushy girl friend like Ran.* [[spoiler:TheSixthRanger: At the finale, Haru finally becomes a member of the Kamen Rider Club with Ran.]]* TookALevelInBadass: Is noteworthy in that his Switch is evolving even before Last One.* UnfortunateNames: Kusao may have been derived from 'kuso', a word with disgusting connotations[[note]]It roughly means "shit"[[/note]], as if hammering home his loser image...or {{foreshadowing}} the whole housefly thing.[[/folder]]
